Consider that heat index readings are for situations in the shade and light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
